Nano science development introduces nano materials which are used into the heat transfer subfields as nano fluids which are produced by dispersing nano particles of metals in the working fluids. Effects of different important parameters in heat pipe drill configuration, such as heat pipe diameter, heat flux input magnitude, length of the heat input zone and depth of the heat pipe within the drill are investigated. A solid cylinder model with conduction mechanism for heat transfer is proposed to simulate the performance of drill approximately. Numerical results from the proposed model are verified by the experimental data. Results indicate the significant effect of using a nano fluid in heat pipe drilling in temperature field reduction. Also, results propose applicable criteria in manufacturing nano fluid heat pipe in drilling.
